Whether or not anyone is interested....
David, son of Avery, was apparently fairly wealthy for the times. Off the top of my head, his residence was at/near Grand Saline (Salina). He apparently had rights to much land (Cherokee don't "own" land -- owning land is like fleas arguing over who owns the dog). Cooper moved his trains to David Van's (sic) during the Bird Creek battle which was apparently on/near the Verdigris. There was also a Van's or Vann's ford on the Verdigris in the vicinity. There is a small lake on the south side of the Verdigris which US Hwy 69 crosses named Van's Lake.
David was killed during the war, perhaps by Pins, and his widow and daughter-in-law(?) shared a house on the west side of the Grand near Ft Gibson with Robert Peck, the author of 'Wagon Boss and Mule Mechanic', and his wife. Peck speaks highly of them, their only flaw being that they were staunch Southerners.
Apparently this David, son of Avery, was in business with Bluford West who owned the salt works on the east side of the Grand just southwest of Locust Grove. When the Eastern Cherokee (Ross Party who came via the 'Trail of Tears') arrived and replaced the existing government of the Western Cherokee (those who migrated west before the forced removals), the new Ross government nationalized all the salt works except those given to Sequoyah as a gift from the government. Bluford lost a lot of money and it appears he believed David Vann had double-crossed him. Bluford went to Washington DC to argue his claim with the War Dept but died of illness while there. (The Treaty Party spent a lot of time in Washington trying to get the US govt to 'protect them and their rights' from the Ross Party, who in 1839 had assassinated three of their leaders sparking the Cherokee Civil War). West's salt works were leased by the Cherokee Nation to Leroy Markham (who married Bluford's widow) and became know as the Markham's Salt Works and I believe they were operated by an Alberty (can't recall which one) and are the same as what is sometimes called 'Alberty's Lick'. Bluford's heirs tried to get restitution for his losses from the Cherokee Nation but it was vetoed by Ross and not paid until after Ross' death.
The attack on David Vann and Isaac Bushyhead at Saline Court House, where Bushyhead was killed, may have been partly retaliation by the Wests. Bluford's brother John W. (my ggg grandfather) and their father Jacob (my gggg grandfather) were tried in a Cherokee court for Bushyhead's death -- the Treaty Party said the trial was a complete farce. Jacob was hanged and John received 100 lashes. One of John's sons was John C. West who was in Watie's Regt and later captain in the US Indian Police. After the war, the Wests lived near Briartown and near John W.'s cousin, Tom Starr. John's youngest son, Franklin P. West (my gg grandfather) and his 2nd cousin Sam Starr (son of Tom, husband of Belle) killed each other in a shoot out near present Whitefield OK. Frank's wife was Nancy Brewer, youngest sister of the Brewers in Watie and Adair's regiments. There is much speculation about who killed Belle Starr but West family lore says "Uncle Pauly did it" in retaliation for the death of Frank.
Way off on a tangent... In the trial of Jacob West, his defense asked the US Govt to intervene because he was 'a white man' (a quaker from Pennsylvania who had immigrated to the Cherokee Nation - East). The US Govt said he had lived in the Cherokee Nation for many years as a full-fledged citizen with a Cherokee wife and children and that the US would not interfere when only Cherokee citizens were involved. When Chief Chad Smith was tribal attorney under Chief Mankiller, he told me that this case is frequently presented in Federal Courts as one example of precidence to show that the Cherokee Nation was not and is not a 'ward of the US government' but is a sovereign (though dependent) nation and was recognized as such by the US govt. The US must regret that decision not to intervene because it means the Cherokee Nation (and by extention the other of the Five Civilized Tribes) can sue the US Govt and the States in the US Federal Courts. The 'reservation tribes' were specifically designated as 'wards of the US Govt' to avoid that 'problem' and have little recourse except through the bureaucracy of the BIA and DOI.
